Gainlab Audio ASW-1

A Selector Designed to Present, Compare, and Route Without Loss

The Gainlab Audio ASW-1 is conceived as a true demonstration hub and monitoring device: it allows feeding up to eight stereo line-level devices, then retrieving their returns to a master output and two headphone outputs. Its principle is simple but highly effective in professional environments: with each selection, the relay switching ensures reliable signal continuity, with a galvanically isolated signal path to preserve audio integrity during comparisons.

Following a studio-oriented, integration, and presentation product line logic, the ASW-1 positions itself as a "central" solution: instead of multiplying repatching, adapters, and wiring errors, you maintain a fixed ergonomics, clear routing, and instant channel switching. The result: you spend more time listening and less time reconfiguring.

Who the ASW-1 Is For: Studio, Showroom, Training, and Integration

In the studio, the ASW-1 serves as a loop selector to compare processing chains, switch from one processor to another, or test multiple devices in a stereo signal flow without touching the wiring. This is particularly relevant for critical listening sessions, quality control, or situations where a known configuration must be quickly recalled.

In a showroom or point of sale, it becomes a clear demonstration tool: one selection and the audio immediately switches to the chosen device, while headphone monitoring allows two people to listen under optimal conditions. In integration (control room, training room, fixed installation), the open collector data output facilitates active channel indication and integrates into control or display systems.

Relays, Headphone Monitoring, and ASW-V Video Option: A Complete and Scalable Platform

Relay Switching and Galvanically Isolated Signal Path

Relay switching is a preferred choice when predictable behavior, clean routing, and consistent sound from channel to channel are desired. Combined with the galvanic connection of the signal path, it helps maintain a robust audio path in comparison, presentation, and monitoring contexts.

Immediate Monitoring: Master Output + Dual Headphone Amplifiers

The ASW-1 does more than select loops: it centralizes listening. With a balanced stereo master output and two integrated headphone amplifiers (TPA6120), you can quickly monitor what is passing through the system without adding an external headphone amp. This approach is ideal for two-person demonstrations, quick channel validation, or monitoring in shared environments.

Loop Naming and Channel Indication

In setups involving multiple machines, clarity is as important as sound quality. Loop naming helps structure your routing (players, processors, destinations), while the open collector data output allows indicating the selected channel on a third-party system according to your installation needs.

ASW-V Option: Audio/Video Demo That Follows Your Selection

With the ASW-V option, the ASW-1 can automatically trigger playback of a video associated with the selected slot. Playback is done from a USB key, without management software, with a FullHD HDMI output. This is a direct asset for digital signage, product presentations, training, or any scenario where the image must remain perfectly aligned with the audio source being demonstrated.
